Erosion and Weathering All Around Us!
We got to focus on a particular beach in Central California that has purple sand! We explored and discussed all the possibilities of where the sand came from and had some great answers such as:
"From the ocean!"
"The cliff and rocks on the beach are purple on the outside".
"The sand turned purple because of something from the water or the sunlight changed the color".
and more amazing answers!
Then, when we found out that there were purple rocks found miles away on a mountain, we realized Rivers must have carried the rocks to the ocean! But how did they get so small? We learned that as the rocks are flowing in the river towards the ocean, it bumps and hits all different things along the way, breaking it up in to smaller and smaller pieces. We then got to practice our new found knowledge with a friendly competition in the S.T.R.E.A.M. Lab! Take a look:
We moved the rocks down the river, breaking it down as we moved from section to section so we could watch the small pile of paper rocks turn in to huge pile of paper sand!
Next up, we will explore and discover different types of Erosion, and how much water changes the landscape around us!
Keep Exploring,
